Hanging Gardens of Babylon

Four acres of garden raised on a base supported by pillars, and
towering in terraces one above another 300 feet in height. At a
distance they looked like a vast pyramid covered with trees. This mound
was constructed by Nebuchadnezzar to gratify his wife Amytis, who felt
weary of the flat plains of Babylon, and longed for something to remind
her of her native Median hills. One of the “seven wonders of the
world.”
